1. A device, comprising:
duty cycle correction circuitry configured to generate, based on an input signal, an output signal having a target duty cycle, the duty cycle correction circuitry comprising:
first circuitry configured to generate a rising edge of the output signal from a rising edge of the input signal, and further configured to generate a falling edge of the output signal based on a feedback signal representative of duty cycle information of the output signal, the first circuitry comprising a first inverter configured to receive the input signal and a second inverter configured to receive the feedback signal.
